What are the components of RGB LED floodlights product?

The RGB LED floodlights product components.

Lens + LED integrated light source (COB) + LED power supply + die-cast aluminum housing = RGB LED floodlights

1, Lens.

Process: There are two kinds, one is physical tempering and the other is chemical tempering.

Physical tempering is the production of ordinary flat glass or float glass by quenching or air-cooling fire treatment under specified conditions and environments.

Chemical tempering is a process in which ordinary flat glass or float glass is subjected to ion exchange to change the composition of the surface of the glass to form a laminated stress layer on the surface of the glass.

Good and bad discrimination: check for quality defects such as flatness, no air bubbles, inclusions, scratches, lines and fog spots. Glass with such defects will be deformed during use, reducing the transparency and mechanical strength of the glass. The thermal stability of the glass.

2, flood cover

Discrimination method: no deformation, no spin lines, no pinholes, bright surface, no obvious sand holes on the surface, good plating gloss, and uniform plating thickness.

3, LED integrated light source

Good or bad identification: whether the chip is required by the microscope (the current large-size chip market is relatively hot, there are Corey, Purui, wafer, etc.), whether the chip size is required for the chip. The chip has square chips, wafers, epitaxial wafers, and flakes, which are confirmed according to the specifications of the RGB LED floodlights manufacturer. The composition of glue, bracket and phosphor also determines the quality of LED products, which are not listed here.

4, LED power supply

Good or bad identification: First we need to start from the data. Such as: enough to buy a 50W RGB LED floodlights, and the supplier gives you the product power of 56W or 46W, both NG. Specific items are measured by the standard at the time of purchase. LED power efficiency conversion rate and power factor determine the quality of the power supply, the better the value is. Non-isolated power supply insulation protection is very important. I heard many customers have said that the LED floodlights that have bought some low-end brand products have the feeling of electric shock, and even more outrageous, there are more than 100 volts of leakage.

5, die-cast aluminum housing

Good or bad identification: The shell determines whether the heat dissipation of this product is good in the future, and whether the light decay is within the normal range. At present, RGB LED floodlights manufacturers are basically used, and the outsourcing kits are assembled. The heat dissipation problem of the products has never been considered. Some manufacturers are very demanding in terms of aluminum for compression costs, and some waste is used. Because the customer has no way to identify the good or bad of aluminum. The best way to tell is to pass the stability test.
